800 "Calorie" diet... Effective surely, but also probably rather hard for many. Surprised by number that managed. Also the difference between average and "some" number seems rather small...
Given my recent experience eating better, I think junk is probably even worse than many people realize.
Refined sugars increase appetite astronomically. When I flipped to healthy food, I had a good few days of "suffering" as my body adjusted to lower calorie intake. After that, I never felt better.
My daily calories are something like 1/4 what they used to be. I lost 10 pounds in a few weeks without even trying. My mental clarity is coming back, which I thought slipped a bit due to age. Maybe age is a factor -- but diet fixed it!
We dont need to eat a lot, not even three meals a day. But we need to eat high quality nutritious food.
I wish the next frontier is actually Food Tech. Which to me may be even more important than Bio Tech. Make organic nutritious affordable with technology.
In the past, I’d get shaky and crabby if I didn’t eat every 2 to 3 hours. Now, I can basically go all day without eating. I frequently feel much better on the days that I don’t end up eating until nearly dinner time.
May be it depends on body type but It really shouldn't take 2 years. If you stop eating carbs and any processed sugar, and I do mean any. And that is with zero calories deficit. i.e Eating as much as you want.
Once you primed your body to know how to burn fat, and sustain it for a period of time, let say at least 7 days and does it regularly Your body will quickly adopt.
I think the key here is that you are not on a calories deficit but simply changing the diet. You can buy some small urine tester to test the state of your body. It generally takes me anywhere from 14 - 21 days before showing the highest level of Ketone. When I am on fasting it took me 7 days.
Once you got to that state, adjusting for Calories deficit becomes much much easier.
